  • Patent number: 7410274
    Abstract: A light guiding unit is provided which can reflect light from one light source such that a plurality of irradiated lights can be intermittently viewed, while allowing substantially all portions of the plurality of irradiated lights to be substantially uniform. The light guiding unit can include an input portion where light from a light source is input, a first reflecting portion that has reflecting surfaces which divide light from the input portion into a plurality of directions (e.g., six directions), and then radially reflects the light. A second reflecting portion can be provided that has reflecting surfaces which reflect light from each of the reflecting surfaces of the first reflecting portion along the principal optical axis. An irradiation portion can be provided that has irradiation surfaces which irradiate light from each of the reflecting surfaces of the second reflecting portion.
